Abstract
A process has been developed for producing diesel boiling range fuel or fuel blending component from renewable feedstocks such as plant oils and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating and/or hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel fuel. The hydrocarbon fraction is isomerized to improve cold flow properties. At least one interstage stream of the hydrogenating and deoxygenating reaction zone is heat exchanged with the feed to the isomerization reaction zone, and/or the effluent of the hydrogenating and deoxygenating reaction zone is heat exchanged with the feed to the isomerization reaction zone.
